    The MV 2.6 Xilinx_edk based TEMAC driver has been posted to this 
list several times.

    As of the last incarnation I tried it had no MII/PHY support and you 
had to manully change the speed of the driver 10/100/1000 by editing the 
code.
    Otherwise it worked with the PLB FIFO TEMAC, that I am using, and 
should with others.

    I have a polled driver that works with the LL TEMAC.
    I am nearly finished a PLB FIFO TEMAC driver that includes working 
autonegotiation and does not use the Xilinx_edk.
    But right now it has a receive problem - packets come in they look 
good but linux silently discards them.

    I have virtually the same code working under GHS Integrity.
